Now, sign in to the website of your domain provider, in my case it is GoDaddy. In GoDaddy portal go to Domains -> Manage DNS as shown in below figure.

Under Manage DNS we need to add three records,
  1. CNAME Record
  2. A Record
  3. TXT Record
Add the CNAME Record and map the default Azure web app service domain name, as shown in the below figure.

Now, we need to enable the CNAME record mapping in Azure; visit the Azure portal and go to a custom domain of the web app service. Click on "Add Custom Domain" icon as shown in the below figure.

Adding A record is to map the Azure web app service IP to the domain.
 
Go to GoDaddy portal - >Domains->Manage DNS -> Edit/Add the A Record and map the Azure web app IP as shown in the below figure.
